Elastic fabric with ventilation effect

ABSTRACT

An elastic fabric may be knitted and made by a plurality of rubber threads, first elastic wefts, second elastic wefts, first wraps, second wraps and winding wraps. The rubber thread, the first elastic weft, and the second elastic weft are elastic, and the first elastic weft and the second elastic weft are knitted across and interlaced with the rubber thread at right angles such that the elastic fabric is configured to be stretched in all directions. The first elastic weft and the second elastic weft are wrapped on at least three rubber threads to form a plurality of breathing holes therebetween, and the first wrap and the second wrap are wrapped along the rubber thread such that the elastic fabric is configured to have the solid structure and the great ventilation effect simultaneously.

FIELD OF THE INVENTION

The present invention relates to an elastic fabric, and more particularly to an elastic fabric with a reliable ventilation effect.

BACKGROUND OF THE INVENTION

Generally, an elastic fabric has been widely used in clothes, sports equipment including knee sleeve, headband and wrist wrap, or medical supplies such as medical bandage. Although the mentioned stuffs have different sizes and weaving methods, they belong to the elastic fabric. In general, a conventional elastic fabric comprises a plurality of elastic wefts and wraps interlaced and knitted with each other to allow the elastic fabric to stretch along directions of wefts and wraps.

However, the conventional elastic fabric has following disadvantages: although the elastic fabric comprises a plurality breathing holes, they always cannot provide sufficient cooling or ventilation effect when used for wrapping on a portion of a user, which may cause the user to appear allergic symptoms such as itching and eczema. Therefore, there remains a need for a new and improved design for an elastic fabric with ventilation effect to overcome the problems presented above.

SUMMARY OF THE INVENTION

The present invention provides an elastic fabric which is knitted and made by a plurality of rubber threads, first elastic wefts, second elastic wefts, first wraps, second wraps and winding wraps. The rubber threads are arranged parallel with each other, and at least three rubber threads as a first group are wrapped by the first elastic weft and the second elastic weft. The weaving process is to repeat an S-shaped and inverted S-shaped pattern along a direction of the rubber thread. More specifically, the first elastic weft and the second elastic weft are configured to wrap across a middle rubber thread first and toward a first adjacent rubber thread at one side of the middle rubber thread. After crossing the first adjacent rubber thread, the first elastic weft and the second elastic weft go back and cross the first adjacent rubber thread, the middle rubber thread and a second adjacent rubber thread at another side of the middle rubber thread, and then go back to cross the second adjacent rubber thread and the middle rubber thread to complete the S-shaped weaving pattern. Then, an inverted S-shaped weaving pattern comes after the S-shaped weaving pattern, the first elastic weft and the second elastic weft are configured to start from an opposed direction to wrap across the middle rubber thread toward the second adjacent rubber thread first, and cross the three rubber threads, and then go back and cross the first adjacent rubber thread and the middle rubber thread to complete the inverted S-shaped pattern. Thus, each of the breathing holes is formed at a gap between a lower portion of the S-shaped weaving and an upper portion of the inverted S-shaped weaving. Furthermore, when the elastic fabric has more than three rubber threads, the second adjacent rubber thread of the first group is served as a first adjacent rubber thread of a second group to keep and extend the weaving pattern. A plurality of junctions are formed at contacting points between the first elastic weft and the rubber thread and between the second elastic weft and the rubber thread. The first wrap and the second wrap, which are made of fabric material such as nylon, charcoal yarn, or cotton yarn, are configured to respectively wrap across an upper surface and a lower surface of the rubber thread. Moreover, the first wrap and the second wrap are knitted and crossed between two lateral sides of the rubber thread in a bit stream pattern along the rubber thread with the same interval to respectively form a top surface and a bottom surface of the elastic fabric. Wherein each of the intervals longitudinally spans two junctions, and each of crossing points on the rubber thread is positioned on the junction. Moreover, each of the winding wraps arranged along the rubber thread comprises a plurality of knot points which are respectively knitted at the junctions and configured to tightly secure positions of the rubber thread, the first elastic weft, the second elastic weft, the first wrap and the second wrap to form the elastic fabric.

Comparing with conventional elastic fabric, the present invention is advantageous because: the rubber thread, the first elastic weft and the second elastic weft are elastic, and the first elastic weft and the second elastic weft are knitted across and interlaced with the rubber thread at right angles such that the elastic fabric is configured to be stretched in all directions. The first elastic weft and the second elastic weft are wrapped on at least three rubber threads to form the breathing holes therebetween, and the first wrap and the second wrap are wrapped along the rubber thread. As a result, the elastic fabric is configured to have the solid structure and the great ventilation effect simultaneously.

In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:

Referring to FIGS. 1 to 3, the present invention provides an elastic fabric (10) which is knitted and made by a plurality of rubber threads (11), first elastic wefts (12), second elastic wefts (13), first wraps (14), second wraps (15) and winding wraps (16). The rubber threads (11) are arranged parallel with each other, and at least three rubber threads (11) as a first group are wrapped by the first elastic weft (12) and the second elastic weft (13). The weaving process is to repeat an S-shaped and inverted S-shaped pattern along a direction of the rubber thread (11). More specifically, the first elastic weft (12) and the second elastic weft (13) are configured to wrap across a middle rubber thread (11) first and toward a first adjacent rubber thread (11) at one side of the middle rubber thread (11). After crossing the first adjacent rubber thread (11), the first elastic weft (12) and the second elastic weft (13) go back and cross the first adjacent rubber thread (11), the middle rubber thread (11) and a second adjacent rubber thread (11) at another side of the middle rubber thread (11), and then go back to cross the second adjacent rubber thread (11) and the middle rubber thread (11) to complete the S-shaped weaving pattern. Then, an inverted S-shaped weaving pattern comes after the S-shaped weaving pattern, the first elastic weft (12) and the second elastic weft (13) are configured to start from an opposed direction to wrap across the middle rubber thread (11) toward the second adjacent rubber thread (11) first, and cross the three rubber threads (11), and then go back and cross the first adjacent rubber thread (11) and the middle rubber thread (11) to complete the inverted S-shaped pattern. Thus, each of the breathing holes (111) is formed at a gap between a lower portion of the S-shaped weaving and an upper portion of the inverted S-shaped weaving. Furthermore, when the elastic fabric (10) has more than three rubber threads (11), the second adjacent rubber thread of the first group is served as a first adjacent rubber thread of a second group to keep and extend the weaving pattern. A plurality of junctions (112) are formed at contacting points between the first elastic weft (12) and the rubber thread (11) and between the second elastic weft (13) and the rubber thread (11). The first wrap (14) and the second wrap (15), which are made of fabric material such as nylon, charcoal yarn, or cotton yarn, are configured to respectively wrap across an upper surface and a lower surface of the rubber thread (11). Moreover, the first wrap (14) and the second wrap (15) are knitted and crossed between two lateral sides of the rubber thread (11) in a bit stream pattern along the rubber thread (11) with the same interval to respectively form a top surface and a bottom surface of the elastic fabric. Wherein each of the intervals longitudinally spans two junctions (112), and each of crossing points on the rubber thread (11) is positioned on the junction (112). Moreover, each of the winding wraps (16) arranged along the rubber thread (11) comprises a plurality of knot points (161) which are respectively knitted at the junctions (112) and configured to tightly secure positions of the rubber thread (11), the first elastic weft (12), the second elastic weft (13), the first wrap (14) and the second wrap (15) to form the elastic fabric (10).

In actual application, referring to FIGS. 2 and 3, the rubber thread (11), the first elastic weft (12) and the second elastic weft (13) are elastic, and the first elastic weft (12) and the second elastic weft (13) are knitted across and interlaced with the rubber thread (11) at right angles such that the elastic fabric (10) is configured to be stretched in all directions. The first elastic weft (12) and the second elastic weft (13) are wrapped on at least three rubber threads (11) to form the breathing holes (111) therebetween, and the first wrap (14) and the second wrap (15) are wrapped along the rubber thread (11). As a result, the elastic fabric (10) is configured to have the solid structure and the great ventilation effect simultaneously.
